Ever since her plane disappeared on her flight around the world in 1937, researchers and conspiracy theorists alike have debated what happened to Amelia Earhart. But now, a study may have pinpointed a new clue that could reveal where she died.

The new study, published in the journal Forensic Anthropology, analyzed bones found on Nikumaroro Island in the South Pacific in 1940, which physician D.W. Hoodless concluded at the time belonged to a male. Those bones have long been lost, but Richard Jantz, a professor emeritus at the University of Tennessee at Knoxville, took a closer look at the measurements using modern technology and found that Hoodless was likely incorrect about the sex of the remains.

Jantz, who conducted the study with the International Group for Historic Aircraft Recovery, looked at the bone lengths and compared them to what we know about the length of Earhart’s bones, including clothing measurements and photographs of her next to scalable objects. Jantz found the previous research dismissing the Nikumaroro bones to be “inadequate,” and concluded that the bones most likely belong to Earhart.

“This analysis reveals that Earhart is more similar to the Nikumaroro bones than 99% of individuals in a large reference sample,” the study noted. “This strongly supports the conclusion that the Nikumaroro bones belonged to Amelia Earhart.”

Jantz believes Earhart died as a castaway on Nikumaroro Island, though some theorists believe she died on Mili Atoll in the Marshall Islands. A press release announcing the findings also notes that the search party which recovered the bones in 1940 also found a part of a woman’s shoe, a box designed to hold a Brandis Navy Surveying Sextant, and a Benedictine bottle, which Earhart had often carried.
